3.0 Warnings 1. Read and understand the entire owner’s manual before attempting assembly or operation.

2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of these warnings may cause serious injury.

3. Replace the warning labels if they become obscured or removed.

4. This jointer is designed and intended for use by properly trained and experienced personnel only. If you are not familiar with the proper and safe operation of a jointer, do not use until proper training and knowledge have been obtained.

5. Do not use this jointer for other than its intended use. If used for other purposes, Powermatic disclaims any real or implied warranty and holds itself harmless from any injury that may result from that use.

6. Always wear approved safety glasses/face shields while using this jointer. Everyday eyeglasses only have impact resistant lenses; they are not safety glasses.

7. Before operating this jointer, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips are recommended. Do not wear gloves.

8. Wear ear protectors (plugs or muffs) during extended periods of operation.

9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities contain chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead based paint.

• Crystalline silica from bricks, cement and other masonry products.

• Arsenic and chromium from chemically treated lumber.

Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area and work with approved safety equipment, such as face or dust masks that are specifically designed to filter out microscopic particles.

10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.

11. Make certain the switch is in the OFF position before connecting the machine to the power supply.

12. Make certain the machine is properly grounded.

13. Make all machine adjustments or maintenance with the machine unplugged from the power source.

14. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches are removed from the machine before turning it on.

15. Keep safety guards in place at all times when the machine is in use, the only exception being special operations such as rabbet cuts which require removal of the cutter guard. If guards are removed for maintenance purposes or special operations, use extreme caution and replace the guards immediately when finished.

16. Check damaged parts. Before further use of the machine, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.

17. Provide for adequate space surrounding work area and non-glare, overhead lighting.

18. Keep the floor around the machine clean and free of scrap material, oil and grease.

5

19. Keep visitors a safe distance from the work area. Keep children away.

20. Make your workshop child proof with padlocks, master switches or by removing starter keys.

21. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts that can result in serious injury.

22. Maintain a balanced stance at all times so that you do not fall or lean against the knives or other moving parts. Do not overreach or use excessive force to perform any machine operation.

23. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for which it was not designed. The right tool will do the job better and safer.

24. Use recommended accessories; improper accessories may be hazardous.

25. Maintain tools with care. Keep knives sharp and clean for the best and safest performance. Follow instructions for lubricating and changing accessories.

26. Turn off the machine before cleaning. Use a brush or compressed air to remove chips or debris — do not use your hands.

27. Do not stand on the machine. Serious injury could occur if the machine tips over.

28. Never leave the machine running unattended. Turn the power off and do not leave the machine until the cutterhead comes to a complete stop.

29. Remove loose items and unnecessary work pieces from the area before starting the machine.

30. Never surface stock less than 12 inches long, or 3 inches wide, or 3 inches thick without a hold-down or push block.

31. When working on the jointer, follow the 3-inch radius rule. The hands must never be closer than 3 inches to the cutterhead. See Figure A.

32. Use extra care in the location of the jointer in the shop. Position the jointer so that potential kicked back stock will strike a wall and not endanger other persons in the area.

33. Never apply pressure to stock directly over the cutterhead. This may result in the stock tipping into the cutterhead along with the operator’s fingers. Follow the 3-inch rule. Position hands away from extreme ends of stock, and push through with a smooth, even motion.

34. “Pull-out” and the danger of kicked back stock can occur when the work piece has knots, holes, or foreign materials such as nails. It can also occur when the stock is fed against the grain on the jointer. The grain should run in the same direction you are cutting.

35. It is good practice to move the hands in an alternate motion from back to front as the work continues through the cut. Never pass the hands directly over the cutter knife. As one hand approaches the knives, remove it from the stock in an arc motion and place it back on the stock in a position beyond the cutter knife. See Figure B. At all times hold the stock firmly.

36. Before attempting to joint or plane, each work piece must be carefully examined for stock condition and grain orientation. NOTE: At certain times it may be necessary to plane against the grain when working with a swirl grain wood or burls. With this type of work the operator must use a lesser depth of cut and a slow rate of feed.

7.0 Assembly Tools need for assembly: 10mm hex wrench (provided) 10-12mm combination wrench (provided) forklift or hoist with straps cross-point screwdriver 1. Remove top and sides of crate from around

the machine.

2. Remove the dust hood and the fence assembly from the skid. Reach into the stand and remove the screws securing the stand to the skid.

3. Raise the jointer off the skid with lifting straps. The straps should be suitable to lift 762 pounds of weight, and should be placed under the base casting as shown in Figure 1. Do not lift the jointer under the infeed and outfeed tables.

4. The jointer should be placed on a sturdy, level floor in a dry area, with sufficient lighting and ventilation. Leave enough room around the machine for loading and offloading stock and routine maintenance work. The machine can be further stabilized by bolting it to the floor using lag screws through the holes on the inside of the stand.

5. This machine is equipped with noise-reducing table lips. The work site should, however, be one which minimizes reverberant sound from walls, ceilings and other equipment.

6. Exposed metal areas of the jointer, including the table and fence surfaces, have been factory coated with a protectant. This should be removed with a soft cloth dampened with a solvent such as mineral spirits or kerosene. Do not use gasoline, acetone or lacquer thinner, and do not use an abrasive pad. Do not let solvent contact the plastic parts of the machine, as it may damage them.

7.1 Fence Installation 1. Use an assistant to help place the fence

assembly on top the table, aligning the holes in the fence assembly with the holes in the table base, as shown in Figure 2.

2. Use the two socket head cap screws and two lock washers (Figure 2), and tighten securely with a 10mm hex wrench.

Figure 1

7.2 Switch Arm The arm (Figure 3) on which the push button switch is located is shipped in the down position. The arm should be pivoted to upright position as shown. Tighten the two screws with a 10mm wrench.

7.3 Dust Hood Before attaching the dust hood, make sure the hole in the dust chute is concealed by the dust chute cover, as shown in Figure 4.

Mount the dust hood to the jointer stand using the seven 1/4 x 1/2 hex cap screws and seven 1/4 lock washers (Figure 5).

It is recommended that a dust collection system of at least 800 CFM be connected to the jointer’s dust hood, via a 4-inch diameter hose.

8.0 Grounding Instructions Electrical connections must

be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury.

This machine must be grounded. Grounding provides a path of least resistance to help divert current away from the operator in case of electrical malfunction.

Make sure the voltage of your power supply matches the specifications on the motor plate of the machine.

Open the junction box (Figure 6) and connect the wires according to the diagram on the inside of the junction box cover. A similar diagram can be found at the back of this manual. The green wire (ground) must be properly grounded.

The Model 1285 may be fitted with an appropriate plug, or be “hard-wired” to an electrical panel. If hard-wired to a panel, make sure a disconnect is available for the operator.

If the jointer is to be hard-wired, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the saw will be connected. Place a warning placard on the fuse holder or circuit breaker to prevent it being turned on while the machine is being wired. Always follow proper Lock-Out/Tag-Out procedures when performing any wiring on this machine.

8.1 Voltage Conversion The Model 1285 Jointer is wired for 1-phase, 230 volt only; or 3-phase, 230/460 volt. The 3-phase model is pre-wired at the factory for 230 volt. However, if you wish to convert your 3-phase jointer from 230 volt to 460 volt, proceed as follows:

1. Disconnect machine from power source.

2. Remove cover from junction box, and open the side door on the stand.

3. Change the wires in the junction box by following the diagram on the inside of the junction box cover, or the diagram found at the back of this manual.

4. Replace the 230 volt contactor (see Figure 7) with the 460 volt contactor (stock no. PJ1285-109B). The 460 volt contactor is available through your authorized Powermatic distributor, or by calling 1-800-274-6848.

5. If you are using a plug on the jointer’s power cord, install an appropriate 460 volt plug.

6. After wiring for the new voltage, turn on the machine and observe the rotation of the cutterhead; it should rotate clockwise when viewed from the front of machine. If it rotates counterclockwise, disconnect jointer from power source and switch any two of the three wires at the junction box.

7. Close junction box and reconnect power.

8.2 Extension cords The use of an extension cord is not recommended, but if one is necessary make sure the cord rating is suitable for the amperage listed on the machine’s motor plate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

Use the chart in Figure 8 as a general guide in choosing the correct size cord. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

9.0 Adjustments Disconnect jointer from

power supply before making adjustments.

9.1 Drive Belt Tension To check the tension of the drive belts:

1. Remove the three cap nuts and flat washers on the pulley cover with a 9/16 wrench, and remove the guard to expose the belts and pulleys. See Figure 9.

NOTE: The hex nuts and flat washers on the threaded rods (A, Figure 9) should be left in place; they keep the pulley cover from bending as it is being tightened back into place with the cap nuts.

2. There should be a small amount of deflection in the belt when pressing it midway between the pulleys with moderate finger pressure (Figure 10).

3. If the belts need tightening, loosen the lower hex nut (A, Figure 11) on the motor base with a 19mm wrench.

4. Turn the top hex nut (B, Figure 11) clockwise until proper tension is achieved.

5. Retighten lower hex nut (A, Figure 11).

NOTE: The belts should be inspected again after the first few times the machine is used, as the belts may stretch slightly during the “breaking-in” process.

9.2 Setting Outfeed Table Height For accurate work in most jointing operations, the outfeed table must be exactly level with the knives/inserts at their highest point of revolution. The outfeed table on the Model 1285 has been pre-set at the factory to the proper height in relation to the cutterhead. However, the level of the outfeed table should be checked in case of slight misadjustment during shipping. Outfeed table height should also be inspected after re-setting or replacing knives/inserts.

1. The outfeed table has a stop screw (A, Figure 12) which, when contacting the edge of the table as shown, will ensure the outfeed table is at the proper height. Loosen the handwheel (C, Figure 12) and raise the outfeed table adjustment arm (D, Figure 12) until this stop screw (A, Figure 12) contacts the edge of the table as shown.

Figure 9

Figure 10

Figure 11

Figure 12

12

2. Place a straight edge on the outfeed table and extending over the cutterhead, as shown in Figure 13.

3. Rock the cutterhead slightly so that a knife tip contacts the straight edge. If the knife tip just contacts the straight edge without moving the straight edge, then the outfeed table is at the proper height. If the knife tip pushes up the straight edge, the outfeed table is too low. If the knife tip does not contact the straight edge, the outfeed table is too high.

4. To raise the height of the outfeed table, loosen the hex nut (B, Figure 12) and rotate the stop screw (A, Figure 12) clockwise. To lower the height of the outfeed table, rotate the stop screw (A, Figure 12) counter clockwise.

5. When the outfeed table is level with the knives, tighten the hex nut (B, Figure 12) and firmly tighten the handwheel (C, Figure 12).

After the outfeed table has been set, it should not be changed except for special operations.

As a final check of the outfeed table adjustment, turn on the jointer and run a scrap piece of wood slowly over the knives for 6 to 8 inches; the wood should rest firmly on both tables, as shown in Figure 14, with no open space under the finished cut.

If the outfeed table is too high, the finished surface of the workpiece will be curved (Figure 15).

If the outfeed table is too low, the workpiece will be gouged at the end of the cut (Figure 16).

Make further changes to the stop screw if necessary to ensure the outfeed table is level with the knives/inserts.

Figure 13

Figure 14

Figure 15

Figure 16

9.3 Setting Infeed Table Height (Depth of Cut)

1. To set the cutting depth, loosen handwheel (A, Figure 17) by turning counterclockwise.

2. Move table adjustment arm (B, Figure 17) up or down to raise or lower infeed table. The pointer (C, Figure 17) shows the depth of cut on the adjoining scale.

3. Tighten handwheel securely (A, Figure 17).

The stop screw (D, Figure 17) on the infeed table should be set so that when it contacts the table, the infeed table will be exactly level with the knives (with the scale pointer at zero). The setting of this stop screw has been made at the factory, but should be checked by the operator before using the jointer. It should also be checked occasionally as the machine receives use.

Use the same procedure as for the outfeed table, placing the straightedge across outfeed table, cutterhead and infeed table. Loosen the hex nut (E, Figure 17) and adjust the stop screw (D, Figure 17) as necessary. When finished, retighten hex nut (E, Figure 17).

If the infeed table is level with the knives but the scale pointer (C, Figure 17) appears to be off, loosen the scale pointer with a screwdriver and adjust it as needed until it reads zero. Retighten the screw.

9.4 Replacing and Setting Knives (Straight Cutterhead)

Jointer knives are very sharp. Use care and proceed slowly when working with or around the cutterhead.

After a period of use, dull knives should be reground or replaced. Remove the pulley cover at the rear of the machine – this will allow you to rotate the cutterhead by using the belts.

To remove a knife:

1. Disconnect machine from power source.

2. Back the fence away from the cutterhead as far as it will go. Lower infeed and outfeed tables.

3. Turn the six gib screws (Figure 18) into the gib with a 10mm wrench. As the pressure of the gib is released, the two springs in the cutterhead slot will cause the knife to rise.

4. Carefully remove the knife from the cutterhead.

Figure 17

Figure 18

14

5. It is recommended when replacing knives that you clean the knife slots in the cutterhead. Remove the gib along with the gib screws, and remove the two springs. Clean the cutterhead slot of any debris or dust that might prevent the knife from seating properly. Also clean the gib, gib screws, and springs. Closely inspect the gib screws – if the threads appear worn or stripped, or if the heads are becoming rounded, replace the screws.

6. Re-insert the springs and the gib.

7. Place the new or resharpened knife into the slot as shown in Figure 18, making sure the direction of the knife is correct.

8. Place the knife setting gauge (provided) upon the cutterhead and centered over a knife, as shown in Figure 19. Make sure the feet of the knife setting gauge rest solidly upon the cutterhead and that its handle is parallel to the cutterhead. The gauge is now holding the knife at proper depth.

9. While keeping the knife setting gauge in place, tighten the six gib screws just enough to hold the knife in position. Start with the center screws first, and work your way toward the end screws.

10. Repeat steps 3 through 9 for the other two knives in the cutterhead. Make the gib screws just tight enough to hold the knives in position.

With all three jointer knives in the cutterhead, the knives should now be tightened incrementally to prevent any buckling or distortion of the cutterhead. Proceed as follows:

11. Rotate the cutterhead to each knife in turn, tightening the gib screws a little more (center screws first, then toward the end screws). Do this at least twice; on the final rotation, firmly tighten all gib screws.

After replacing and checking knives, check again carefully. Make certain the direction of knives is correct, and all eighteen gib screws are tightened securely. Loose gib screws can result in knives being thrown from the cutterhead, causing severe damage to the machine and possible serious or fatal injury to the operator or bystanders.

Figure 19

9.5 Replacing Knife Inserts (Helical Cutterhead)

Jointer knife inserts are very sharp. Use care and proceed slowly when working with or around the cutterhead.

The helical cutterhead is a solid steel design that holds 42 two-sided knife inserts, and two rabbet knife inserts on the outboard end of the cutterhead. Replacing knife inserts is a simple process, and they will seat themselves properly without having to be set with a knife gauge.

After a period of use, dull knife inserts should be flipped over to present a new edge. If both edges are worn, knife inserts should be replaced.

1. Loosen the gib screw (A, Figure 20).

2. Remove the knife insert (B, Figure 20) with the gib (C, Figure 20) from its slot.

3. Make sure the slot (D, Figure 20) is free of dust and debris that would prevent the gib and insert from seating properly. Wipe out the slot and clean with solvent if needed.

4. Flip the knife insert 180 degrees and place it onto the two pins of the gib. Make sure the knife edge faces the proper direction (see Figure 21).

5. Re-install the gib into the slot.

6. Firmly tighten the gib screw (A, Figure 20).

NOTE: To ensure optimal cutting, all knife inserts in the cutterhead should be flipped at the same time. Of course, if an insert is nicked or damaged, it can be flipped or replaced individually as needed.

After installing a knife insert, be sure to tighten the gib screw before moving on to the next knife insert.

Make certain the direction of knife inserts is correct, and all gib screws are tightened securely. Loose gib screws can result in knife inserts being thrown from the cutterhead, causing severe damage to the machine and possible serious or fatal injury to the operator or bystanders.

9.6 Fence Adjustments The fence (A, Figure 22) tilts backward and forward to 45 degrees. It has a 90-degree stop (B, Figure 22) and a 45-degree stop (C, Figure 22).

To tilt fence forward: 1. Loosen the lock handle (D, Figure 22) and

tilt the fence forward using the handle (E, Figure 22). NOTE: Lift up slightly on the fence while tilting it, to prevent scratching the table surface.

2. Retighten lock handle (D, Figure 22).

To tilt fence backward:

1. Loosen the lock handle (D, Figure 22) and pivot the stop block (F, Figure 22) out of the way.

2. Tilt the fence using the handle (E, Figure 22). NOTE: Lift up slightly on the fence while tilting it to prevent scratching the table surface.

3. Retighten lock handle (D, Figure 22).

To move fence forward or backward:

1. Loosen lock handle (G, Figure 22) and rotate handwheel (H, Figure 22); counterclockwise for forward fence movement, clockwise for backward fence movement.

2. When desired position is reached, securely tighten lock handle (G, Figure 22).

To check and adjust the 90-degree stop:

1. Loosen lock handle (D, Figure 23) and tilt fence until the stop screw (B, Figure 23) contacts the stop block (F, Figure 23).

2. Place a square or machinist’s protractor (not provided) on the table and flush against the fence surface. See Figure 23.

3. If adjustment is necessary, loosen the hex nut on the stop screw (B, Figure 23) and turn the stop screw as needed until the fence is flush with your square.

4. Retighten the hex nut.

Figure 22

Figure 23

17

To check and adjust the 45-degree stop:

1. Loosen lock handle (D, Figure 22) and tilt fence until it contacts the 45-degree stop (C, Figure 22).

2. Place a machinist’s protractor or similar device set at 45 degrees on the table and against the fence.

3. If adjustment is necessary, loosen the hex nut on the stop screw (C, Figure 22) and turn the stop screw until the fence is flush with the protractor.

4. Retighten the hex nut.

9.7 Cutter Guard Tension The tension of the guard (Figure 24) must always be sufficient during jointer operations to cause the guard to conceal the unused part of the cutterhead, and to swing back to contact the fence after the workpiece has cleared the cutterhead. To adjust the guard tension:

1. Loosen the knob shown in Figure 24 and push the knob to the right to increase guard tension; or to the left to decrease guard tension.

2. Tighten the knob in that position.

10.0 Operating Controls The push button on/off switch is conveniently positioned above the table (Figure 25). Do not remove the clear plastic cover, as this keeps wood dust out of the switch.

11.0 Operation Before operating the 1285

Jointer, make sure knives are properly tightened. On helical head models, verify that each of the inserts is properly torqued down.

NOTE: If you are inexperienced at jointing, use scrap pieces of lumber to check settings and get the feel of operations before attempting regular work.

Always use the guard whenever possible and keep hands away from cutterhead. Failure to comply may cause serious injury.

Ideally, the fence should be moved forward (toward the front of the machine) to expose only the amount of cutterhead needed for the workpiece.

Figure 24

Figure 25

18

TIP: If workpieces of the same size are constantly being run on the jointer, the operator may wish to occasionally adjust the fence forward or backward to prevent wear on only one area of the knives.

11.1 Hand Placement At the start of the cut, the left hand holds the workpiece firmly against the infeed table and fence, while the right hand pushes the workpiece toward the knives. After the cut is under way, the jointed surface of the workpiece rests firmly on the outfeed table. The left hand should press down on this part, at the same time maintaining flat contact of the workpiece with the fence. The right hand pushes the workpiece forward and before the right hand reaches the cutterhead, the right hand should be moved to the workpiece on the outfeed table. The workpiece is then pushed on through to complete the cut. Follow the 3-inch rule (see page 5). Never pass hands directly over the cutterhead.

11.2 Edge Jointing This is the most common operation for the jointer. Set the fence to the 90-degree stop and thus square with the table. Depth of cut should be the minimum required to obtain a straight edge. Do not make cuts deeper than 1/8” in a single pass. Hold the best face of the workpiece firmly against the fence throughout the feed. See Figure 26.

11.3 Surfacing Jointing the face of stock, or surfacing is shown in Figure 27. Adjust the infeed table for depth of cut. Cuts of approximately 1/16” at a time are recommended, as this allows better control over the material being surfaced. More passes can then be made to reach the desired depth.

Always use a hold-down or push block when surfacing short stock or stock less than 3 inches thick. Figure 26 shows push blocks being used for surfacing.

11.4 Rabbeting A rabbet is a groove cut along the edge of a workpiece. See Figure 28. The width and thickness of the workpiece used will be dependent upon the desired width and length of the rabbet. However, never rabbet a workpiece less than 12 inches long.

Figure 26

Figure 27

Figure 28

19

A rabbet cut requires removal of the cutterhead guard. Use extreme caution and keep hands clear of cutterhead. Always replace guard immediately after rabbeting operation is completed.

Use push blocks to rabbet cut whenever possible. The rabbeting capacity is 3/4”.

1. Disconnect machine from power source.

2. Set fence for desired width of rabbet.

3. Check width of the rabbet by measuring the distance from the end of a knife in the cutterhead to the fence.

4. Reconnect power. Lower the infeed table 1/32” at a time and make successive cuts until the desired depth of rabbet has been obtained. See Figure 28. NOTE: It is easier and safer to take a series of shallow cuts.

11.5 Jointing Warped Surfaces If the wood to be jointed is dished or warped, take light cuts until the surface is flat. Avoid forcing such material down against the table; excessive pressure will spring it while passing the knives, and it will spring back and remain curved after the cut is completed.

11.6 Jointing Short or Thin Work When jointing short or thin pieces, use a push block to eliminate all danger to the hands. Two push blocks are shipped with your jointer, and additional ones can be purchased from most hardware or machine tool stores. You can also make your own easily from scrap material. Three types of commonly used push blocks are represented in Figure 29.

11.7 Direction of Grain Avoid feeding work into the jointer against the grain. This will result in chipped and splintered edges. See Figure 30. Feed with the grain to obtain a smooth surface, as shown in Figure 31.

11.8 Beveling To cut a bevel, lock the fence at the required angle and run the workpiece across the knives while keeping it firmly against the fence and tables. Several passes may be necessary to achieve the desired result.

While the fence can be tilted in or out for bevel cutting, it is recommended for safety reasons that the fence be tilted in toward the operator, if possible, making a cradled cut.

12.0 Maintenance Disconnect machine from

power source before performing any maintenance. Failure to comply may cause serious injury.

Check all screws and fasteners occasionally and keep them tightened securely.

Inspect cords; a cord that is frayed or damaged in any way should be replaced immediately.

The table and fence surfaces must be kept clean and free of rust for best results. Some users prefer a paste wax coating. Another option is talcum powder applied with a blackboard eraser rubbed in vigorously once a week; this will fill casting pores and form a moisture barrier. This method provides a table top that is slick and allows rust rings to be easily wiped from the surface. Important also is the fact that talcum powder will not stain wood or mar finishes as wax pickup does.

12.1 Lubrication The cutterhead runs in two single-row sealed and shielded ball bearings, which are pre-lubricated for life - no maintenance is necessary.

Occasionally apply a good grade of light grease to areas of the jointer where friction may occur, such as when the tables are raised or lowered.

12.2 Cutterhead Repairs The entire cutterhead assembly may be removed for bearing replacement or other cutterhead maintenance procedures. The procedure is identical for both helical and straight cutterheads.

To remove the cutterhead:

1. Disconnect machine from power source.

2. Remove rabbeting ledge and fence.

3. Lower infeed and outfeed tables until they are clear of the cutterhead.

4. Remove belts.

5. Remove the two hex cap screws and lock washers that hold the cutterhead to the bed – these are accessed from the underside of the bearing blocks as shown in Figure 32.

Before removing cutterhead, wrap it with several cloths to prevent personal injury.

Figure 32

21

6. Slide the cutterhead out the rabbeting side.

7. Loosen hex cap screw (A, Figure 33) and remove pulley (B, Figure 33) and key (C, Figure 33).

8. Loosen screws (D, Figure 33) on both sides and remove bearing cap plates (E, Figure 33).

NOTE: Figure 33 shows the pulley end of the cutterhead. The procedure is similar for breaking down the opposite end of the cutterhead – refer to assembly drawing on page 39 for the specific parts.

IMPORTANT: If the bearings (G, Figure 33) need replacement, it is strongly recommended this be done by qualified service personnel. The bearings are press fitted and must be removed with an arbor press.

9. To re-install the cutterhead, reverse the above procedure. NOTE: Before re-installing, make sure the machine’s curved seats of the base casting are free of dirt, dust or grease, which will help ensure a tight fit.

12.3 Knife Inserts (Helical Cutterhead)

When knife inserts become dull enough so that it is noticeable when cutting, they should be turned over or replaced entirely. A sharp knife works easier and results in longer blade life. The penalty paid for a dull knife is less blade life and greater wear and tear on all parts of the machine.

An advantage of the helical style cutterhead is that if knife inserts develop nicks, these inserts can be individually flipped or replaced without the need to disturb the other inserts. See “Replacing Knife Inserts (Helical Cutterhead)” for this procedure.

If the jointer is used often, keeping a spare set of knife inserts on hand is recommended. Knife inserts (stock no. 6400013) may be ordered from your authorized Powermatic distributor or by calling 1-800-274-6848.

Gum and pitch which collect on the knife inserts cause excessive friction as the work continues, resulting in overheating of the inserts, less efficient cutting, and consequent loss of blade life. Use "Gum and Pitch Remover" or oven cleaner, to carefully wipe off the knife inserts.

Jointer knife inserts are very sharp. Use care and proceed slowly when working with or around the cutterhead.

Figure 33

22

12.4 Whetting Knives (Straight Cutterhead)

When knives become dull enough so that it is noticeable when cutting, they should be resharpened or replaced. A sharp knife will work easier and last longer. The penalty paid for a dull knife is less blade life and greater wear and tear on all parts of the machine.

Jointer knives are very sharp. Use care and proceed slowly when working with or around the cutterhead.

1. Disconnect machine from power source.

2. Remove the pulley cover so you can rotate the cutterhead by means of the belts.

3. Use a fine carborundum stone. Cover it partly with paper, as shown in Figure 34, to avoid marking the table.

4. Lay the stone on the infeed table. Adjust the infeed table and turn the cutterhead until the stone lies flat on the bevel of the knife and flat on the infeed table.

5. Hold the cutterhead from turning, and whet the beveled edge of the knife, stroking lengthwise by sliding the stone back and forth across the table. Do the same amount of whetting on each of the three knives.

6. When finished, reset the knives parallel to the outfeed table. See “Setting Knives (Straight Cutterhead)”.

If knives cannot be properly retouched as described above, they must be ground and re-surfaced to a new bevel edge. Check in the phone directory under “Sharpening Service” or “Tool Grinding or Sharpening.” It may be less expensive to purchase a new set of knives. If the jointer is used often, keeping a spare set of knives on hand is recommended.

Knives (stock no. 6292535) may be ordered from your authorized Powermatic distributor or by calling 1-800-274-6848.

Gum and Pitch which collect on the knives cause excessive friction as the work continues, resulting in overheating of the knives, less efficient cutting, and consequent loss of blade life. Use "Gum and Pitch Remover" or oven cleaner, to carefully wipe off the knives.

Figure 35

Ends of finished stock are cut more than the middle.

Table ends are raised higher than the middle.

Lower both table ends using the adjustment screws under the tables (see Figure 35).

Chip out. Cutting against the grain. Cut with the grain whenever possible.

Dull knives/inserts. Sharpen or replace knives/inserts.

Feeding workpiece too fast. Use slower rate of feed.

Cutting too deeply. Make shallower cuts.

Knots, imperfections in wood. Inspect wood closely for imperfections; use different stock if necessary.

Fuzzy grain. Wood has high moisture content. Allow wood to dry or use different stock.

Dull knives/inserts. Sharpen or replace knives/inserts.

Cutterhead slows while operating.

Feeding workpiece too quickly, or applying too much pressure to workpiece.

Feed more slowly, or apply less pressure to workpiece.

“Chatter” marks on workpiece.

Knife/inserts incorrectly set. Set knives properly using provided knife setting gauge (straight cutterhead only – see section 9.4). Check that insert slots are clean and free of dust or debris (helical cutterhead only).

Feeding workpiece too fast. Feed workpiece slowly and consistently.

Uneven knife marks on workpiece.

Knives/inserts are knicked, or out of alignment.

Replace knicked knives/inserts; align knives properly with knife-setting gauge (straight cutterhead only).

13.2 Mechanical and Electrical Problems Trouble Probable Cause RemedyMachine will not start/restart or repeatedly trips circuit breaker or blows fuses.

No incoming power. Verify unit is connected to power, and on-switch is pushed in completely.

Overload automatic reset has not reset.

When jointer overloads on the circuit breaker built into the motor starter, it takes time for the machine to cool down before restart. Allow unit to adequately cool before attempting restart. If problem persists, check amp setting on the motor starter inside the electrical enclosure.

Jointer frequently trips.

One cause of overloading trips which are not electrical in nature is too heavy a cut. The solution is to take a lighter cut. If too deep a cut is not the problem, then check the amp setting on the overload relay. Match the full load amps on the motor as noted on the motor plate. If amp setting is correct then there is probably a loose electrical lead. Check amp setting on motor starter.

Building circuit breaker trips or fuse blows.

Verify that jointer is on a circuit of correct size. If circuit size is correct, there is probably a loose electrical lead. Check amp setting on motor starter.

Motor starter failure.

If you have access to a voltmeter, you can separate a starter failure from a motor failure by first, verifying incoming voltage at 230+/-20 and second, checking the voltage between starter and motor at 230+/-20. If incoming voltage is incorrect, you have a power supply problem. If voltage between starter and motor is incorrect, you have a starter problem. If voltage between starter and motor is correct, you have a motor problem.

Motor overheated. Clean motor of dust or debris to allow proper air circulation. Allow motor to cool down before restarting.

Motor failure.

If electric motor is suspect, you have two options: Have a qualified electrician test the motor for function or remove the motor and take it to a qualified electric motor repair shop and have it tested.

Miswiring of the unit.

Double check to confirm all electrical connections are correct and properly tight. The electrical connections other than the motor are pre-assembled and tested at the factory. Therefore, the motor connections should be double checked as the highest probability for error. If problems persist, double check the factory wiring.

On/off switch failure.

If the on/off switch is suspect, you have two options: Have a qualified electrician test the switch for function, or purchase a new on/off switch and establish if that was the problem on changeout.
